DSB 3
Model DSB 3 is a fully hydraulically operated rotary drilling rig equipped with
the worldwide patented NORDMEYER round drilling mast and the built-in hydraulic drill feed. By means of special cable arrangements (2-fold or 4-fold cable pull) the hydr. powerhead and the drill string can be pulled up to the max. hook load to achieve higher pulling forces.
The high pull on the powerhead allows for relatively high weight of drill collars granting
a centrical pull-down on the drill bit and a pressure relief on the drill string, the most favourable conditions for safe and fast vertical drilling.
Applications
- Prospective drilling (core drilling)
- Drilling of monitoring wells
- Water well drilling for water supply or irrigation
- Geological and hydrological testing
- Soil sampling
Drilling methods
- Dry drilling
up to max. dia. 1120 mm in front of the mast (1220 mm on request)
- Cable percussion drillings
for casings up to max. dia. 419 mm
- Undisturbed soil sampling
by drive sampler BPE, drive sampler RKR, cable guided peumatic hammer
- Rotary core drillings
by single tube, double tube or wire line core barrel
- - Direct rotary flush drilling
up to max. borehole dia. 17 ½ = 445 mm
- Reverse circulation drilling
with suction pump, or air lift drilling with compressor up to max. borehole dia. 1120 mm(1220 mm on request) in front of the mast
- DTH-Hammer drilling
with stand-by compressor up to borehole dia. 17 ½" = 445 mm
